Chemical Structure
Description
The occurrence of Phentolamine-d4 HCl (Regitine-d4 HCl) is closely related to deuterium isotope labeling, a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Phentolamine-d4 HCl (Regitine-d4 HCl) (CAS 1346599-65-2) is a high-purity analytical reference standard with the molecular formula C17H15D4N3OHCl and a molecular weight of 321.84 g/mol.
Owing to deuterium isotope labeling, a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, Phentolamine-d4 HCl (Regitine-d4 HCl) is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 321.84 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
